Comprised of diatomaceous earth, which is made of fossilized water plants so tiny and sharp that they lacerate the insect body and cause death by dehydration within 48 hours. Because it works mechanically upon the insects, they won't develop immunity. It may be safely applied indoors or outdoors, around home foundations, in corners and crevices inside. So safe you can actually rub it into your dog or cat's fur. If you apply with a duster, wear protective gear to avoid inhaling dust. Not effective when it gets wet, but regains effectiveness when it dries out. Controls ants, fleas, ticks, cockroaches, earwigs, slugs, beetles, and silverfish. 6 lb bag treats 2500 sq. ft.
13.5 x 4 x 8 inches.
